I had a similar problem in a site I’m working on. I don’t have the code with me right now but I think I did something along these lines:

if request.method == 'POST': 
    valid = False
    form = FormOne(request.POST) 
    if form.is_valid():
        #handle case where use submitted FormOne
        valid = True

    form = FormTwo(request.POST) 
    if form.is_valid():
        #handle case where use submitted FormTwo
        valid = True

    form = FormThree(request.POST) 
    if form.is_valid():
        #handle case where use submitted FormThree
        valid = True

    if not valid:
        #handle case where none of the forms were valid

The correct way to handle multiple forms is by using the “prefix” attribute when you create your forms. This is how your view should looks like:

if request.method == 'POST':
    form1 = Form1(request.POST, prefix='form1')
    form2 = Form2(request.POST, prefix='form2')
    form3 = Form3(request.POST, prefix='form3')

    if form1.is_valid() and form2.is_valid() and form3.is_valid():
        # Do whatever you have to do
        pass

else:
    form1 = Form1(prefix='form1')
    form2 = Form2(prefix='form2')
    form3 = Form3(prefix='form3')

The template remains the same, no extra logic needed in there:

<form ...>
    {{ form1.as_table }}
    {{ form2.as_table }}
    {{ form3.as_table }}

    <input type="submit" ... />
</form>

  1. My first thought is you can add a ‘?form_id=1’ to each forms action attribute.

    <form action="?form_id=1" method="post" id="form-one">

    In the view:

    form_id = request.GET.get('form_id', None)
if form_id == '1':
    form_one = FormOne(request.POST)

  2. Another option would be to create separate urls to post to.

    in urls.py

    url(r'^form1/$', 'someapp.views.process_forms', {'form_class': FormOne}, name='form_one_page'),
url(r'^form2/$', 'someapp.views.process_forms', {'form_class': FormTwo}, name='form_one_page'),
url(r'^form3/$', 'someapp.views.process_forms', {'form_class': FormThree}, name='form_one_page'),

    in views.py:

    def process_forms(request, form_class=None):
    ...
    form = form_class(data=request.POST)
    ...

  3. You can check if submit button name since your using them in your submit button.

    if request.POST.has_key('form-one'):
    ...
elif request.POST.has_key('form-two'):
    ...
elif request.POST.has_key('form-three'):
    ...
else:
    ...
